Investigation of Backward Reflection from Aqueous Media at Arbitrary Grazing Angles

Abstract

A model of backward reflection is presented which is distinguished by the fact that it takes account of excitation of counterpropagating waves in bounding media. For the case of a homogeneous aqueous medium, it is shown that the proposed model describes distinguishing features of the angular dependence of the backward reflection coefficients for all angles of incidence of the waves on the air–water interface. Characteristic regions of the angular dependence, associated with different mechanisms of formation of the backward reflection, are elucidated.
